Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have built a superconducting camera containing 400,000 pixels — 400 times more than any other device of its type. Superconducting cameras allow scientists to capture very weak light signals, whether from distant objects in space or parts of the human brain. Having more pixels could open up many new applications in science and biomedical research. The NIST camera is made up of grids of ultrathin electrical wires, cooled to near absolute zero, in which current moves with no resistance until a wire is struck by a photon. In these superconducting-nanowire cameras, the energy imparted by ...

A study led by UCLA researchers found that the children of parents who experienced adverse childhood experiences (ACEs)– such as abuse, neglect, violence in the home, or loss of a parent – are at increased risk of arrests and convictions by young adulthood. The authors report that their findings suggest that there is a crucial need for prevention of ACE exposure in the first place, as well as efforts to mitigate the impact of ACEs before they have downstream impacts on the next generation of children who are not yet born. The study appears in JAMA ...

Scientists have observed the creation of rare chemical elements in the second-brightest gamma-ray burst ever seen – casting new light on how heavy elements are made. Researchers examined the exceptionally bright gamma-ray burst GRB 230307A, which was caused by a neutron star merger. The explosion was observed using an array of ground and space-based telescopes, including NASA’s James Webb Space Telescope, Fermi Gamma-ray Space Telescope, and Neil Gehrels Swift Observatory. Publishing their findings today in Nature (25 Oct), ...

The first data from the InSight mission made it possible to determine the internal structure of Mars in a series of papers from the scientific team published in the summer of 2021. However, since then, the analysis of new data generated by a powerful meteorite impact that occurred on September 18 2021, questioned the first estimates of the internal structure of the Red Planet. By studying the propagation times of waves generated by this impact, an international team led by Henri Samuel, CNRS researcher at the Institut ...

NASA’s InSight mission to Mars helped scientists map out Mars’ internal structure, including the size and composition of its core, and provided general hints about its tumultuous formation. But findings from a new paper published in the journal Nature could lead to reanalysis of that data. An international team of researchers discovered the presence of a molten silicate layer overlying Mars’ metallic core—providing new insights into how Mars formed, evolved and became the barren planet it is today. Published on October 25, 2023, the team’s paper details the use of seismic data to locate and identify a thin layer of molten ...

Scientists have long debated the Anthropocene Epoch, a proposed unit of geologic time corresponding to the most recent period in history. It’s characterized by substantial human impact on the planet. Are we living in the Anthropocene? And if we are, then when did it start?  In a research article published this month in The Proceedings of the National Academy of Sciences, The University of Toledo’s Dr. Trisha Spanbauer and Stanford University’s Dr. M. Allison Stegner lend credence to the argument for its existence. The pair analyzed open-source data to track vegetation ...

Key takeaways 47.5% of respondents ages 13–24 feel most TV shows and movie plots don’t need sexual content; 51.5% want to see more focus on friendships and platonic relationships. 56% of those aged 10–24 prefer original content over franchises and remakes. Twice as many adolescents prefer binge releases over weekly drops. Adolescents want to see lives like their own depicted on screen. This year’s Teens & Screens report from UCLA’s Center for Scholars & Storytellers, or CSS, found that teens — plus the 18- to 24-year-old demographic that advertisers typically ...

Existing air pollution regulations will reduce thousands of premature adult deaths in the UK, but even the most effective technically feasible actions, which will save thousands more lives, will do little to protect the country’s sensitive ecosystems, find UCL researchers. The new research, published in GeoHealth, found that existing air pollution regulations could avoid 6,751 early deaths amongst adults in the UK by 2030 compared to if no regulations existed. That estimate nearly doubles to 13,269 avoided adult premature deaths if all possible technically feasible measures are employed to reduce air pollution immediately.  However, existing regulations don’t ...

It’s the day after the Baltimore Orioles clinched the American League East Championship with their 100th win of the season, and lifelong fan Tim Evans is showing his pride on his sleeve. “It’s so great,” Evans, 62, says with a huge smile, wearing his orange O’s jersey. The last time the Orioles won the AL East was in 2014, the same year Evans was diagnosed with amyotrophic lateral sclerosis (ALS), a progressive nervous system disease that causes muscle weakness and loss of motor and speech functions. Evans currently has severe speech and swallowing problems. He can talk slowly, but it’s hard for most people to understand him.   However, ...

(LOS ANGELES) – October 25, 2023 - The Terasaki Institute for Biomedical Innovation (TIBI) has developed a novel organ-on-a-chip device for measuring electrical resistance across endothelial barriers. This chip had carbon-based, screen-printed electrodes incorporated into a multi-layered, microfluidic chip fabricated by a simple and cost-effective method. Endothelial cells line blood and lymph vessels of the body and form a barrier layer which controls the flow of fluid and substances to and from the vessels and surrounding tissues. Study of the crucial roles ...

Opening a clamshell of berries and seeing them coated in fuzzy mold is a downer. And it’s no small problem. Gray mold and other fungi, which cause fruit to rot, lead to significant economic losses and food waste. Now, researchers report in ACS’ Journal of Agricultural and Food Chemistry that compounds from sunflower crop waste prevented rotting in blueberries. They suggest the food industry could use these natural compounds to protect against postharvest diseases. Sunflowers are cultivated around the world for their seeds and oil, but the flower stems — known as receptacles — are generally considered to be a waste product. Noting that this crop is particularly ...

His leadership through one of the most challenging times in history—the COVID-19 pandemic—serves ...

Pork production is a societal concern on several fronts: antibiotics use, infectious disease, poor animal welfare and climate and environmental pressures. Even though the beef, coffee and chocolate industries are each major climate culprits, the world's total consumption of pork emits hundreds of millions of tons of CO2 every year. But are you willing to fork over extra cash for a more climate-friendly pork roast? Or, are there other considerations that would increase your willingness to pay more? And if so, how much of a premium would you be willing to pay? Researchers from the University of Copenhagen’s Department of Food and Resource Economics investigated ...

Studying the brain remains one of the most challenging endeavors in neuroscience. Researchers have explored various methods for live imaging and stimulation of deep brain activity. One such method is multiphoton excitation using pulsed infrared (IR) light. This type of light is weakly absorbed by tissues and can penetrate through the bone and deep into organs like the brain. However, it has its limitations to produce focused images and to control cellular activity with precision. To overcome this, scientists have been exploring three-photon excitation with ultrafast pulsed IR light, to achieve ...

New research from King’s College London has found that in the UK people with severe mental illness were at increased risk of death from all causes following COVID-19 infection compared to those without severe mental illness. Published in the British Journal of Psychiatry, the study investigated the extent to which having severe mental illness, which includes schizophrenia and psychosis, increased the risk of death during the first two waves of the COVID-19 pandemic. Researchers at the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) and ESRC Centre for Society and Mental Health analysed data from over 660,000 ...
